The interface box requires 10-16 VDC power
input supporting 50 watts
(4.2 amps @ 12 VDC).
Follow these steps to connect power to the
interface box.
a.
Before you connect the power wires, turn off
vessel power and test the circuit to ensure no
power is present.
b.
Connect the individual power wires to a
dedicated 10-amp or 15-amp circuit breaker.
Connect the negative (black) wire to ground
(power return), and connect the positive (red)
wire to +12 VDC vessel power.
c.
Plug the other end of the wires into the
“Power” jack on the rear panel of the
interface box (see Figure 21).
NOTE:
Do not remove the small ferrite coil that is
clamped onto the power wires. This coil suppresses
EMI (electromagnetic interference) from the interface
box.
d.
Connect power to the receiver(s). Follow the
instructions in the receiver’s manual.
CAUTION
For your own safety, shut down vessel
power before you connect the wires.
